Granted: 1982-11-05
Abstract: The object of this system is to present a control system of level in a gab which shows prompt response and stability.  When the error is out of a gap, it feeds back control output signal computed by the average of influx or effluence.  When the error is in a gap, it produces the computed signal.  In Fig.1 LC is a level control device, FC is a flux control device.  Both devices are connected in series.  The LC is primary, and FC is secondary.  In Fig.2 if level h rises from a gap, influx is reduced and feedback of level h is performed.  IF level h comes in a gap, control action dies out.

IPC: C22F1/08
Filed: 1980-12-16
Granted: 1985-06-14
Abstract: The final drawing process in the prodn. of copper tubes is carried out by using drawing oil. This operation is followed by annealing the tubes which also burn-off the residual drawing oil. The operation is normally carried out as a batch process in separate furnaces and tends to leave a deposit of carbon on the inside surface of the tubes. In this continuous annealing process an induction or resistance method of heating the tubes is used while connecting each length to the preceding one with a connector permeable to gas. Oxygen enriched air is passed through the tubes to reduce the amt. of residual carbon deposted on the inside surface of the tubes.
